http://security.gentoo.org/

Severity:	normal
Title:	BeanShell: Arbitrary code execution
Date:	07/30/2016
Bugs:	#575482
ID:	201607-17

Synopsis

BeanShell is vulnerable to the remote execution of arbitrary code via Java serialization or XStream from an untrusted source.

Background

BeanShell is a small, free, embeddable Java source interpreter with object scripting language features, written in Java.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
dev-java/bsh	< 2.0_beta6	>= 2.0_beta6	All supported architectures

Description

An application that includes BeanShell on the classpath may be vulnerable if another part of the application uses Java serialization or XStream to deserialize data from an untrusted source.

Impact

Remote attackers could execute arbitrary code including shell commands.

Workaround

There is no known workaround at this time.

Resolution

All BeanShell users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --verbose --oneshot ">=dev-java/bsh-2.0_beta6"
